List of largest planets in solar system

What is the largest planet in the Solar System?

Earth is the largest terrestrial or inner planet. Our solar system comprises eight planets, which fall into two categories: the smaller, rocky inner planets (Mercury, Venus, Earth, and Mars) and the larger, gas giants (Jupiter, Saturn, Uranus, and Neptune). Another name for the gas giants is the Jovian planets, for their similarity to Jupiter.

What are the smallest and largest planets in order?

The size of the planets in order from smallest to largest is Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter. The size of planets in our solar system varies dramatically. Let’s explore the sizes of the planets, including their radius and diameter in both kilometers and miles, and their relative sizes compared to Earth.

Are Jupiter and Saturn the largest planets in the Solar System?

The outer solar system contained vast amounts of hydrogen and helium, allowing planets like Jupiter and Saturn to become the largest planets in the solar system. Interestingly, Jupiter and Saturn are probably the two most similar planets in the solar system. Both are composed chiefly of hydrogen and helium and are covered in large bands of gas.

How many planets are in the Solar System?

Our solar system comprises eight planets, which fall into two categories: the smaller, rocky inner planets (Mercury, Venus, Earth, and Mars) and the larger, gas giants (Jupiter, Saturn, Uranus, and Neptune). Another name for the gas giants is the Jovian planets, for their similarity to Jupiter. Pluto is a dwarf planet, but it’s also included here.

Which planets are gas giants?

As gas giants, these planets don’t have a solid surface like terrestrial planets and consist mainly of gases (hydrogen and helium). Uranus would round out the top three as the third largest planet in the solar system, but it doesn’t come close to even the size of the second largest planet, Saturn. In fact, Jupiter is 2.8x larger than Uranus.

If you’re interested in planets, the good news is there’s plenty of variety to choose from in our own Solar System.
